Is it possible to create an environmentally friendly shampoo? Learners accept this challenge in the fifth instructional activity in a green chemistry series of 24. The analysis of their shampoo ingredients must address pH, exothermic...

In this solutions activity, learners answer questions about the solubility of various substances in solvents such as oil in water and nitrogen gas in helium. They draw water molecules to show bonding between them and they diagram a flask...

Hydrogen bonds, and polarity are described in this PowerPoint, and the reasons for tension and cohesion associated with water.  The states of water under certain conditions are explained with information about the changes in...

To conclude a mini unit on the dissolving of M&Ms® candy coating, this lesson plan investigates whether or not the concentration of sugar in the solvent affects the dissolving rate. Consider having older science learners write their...

Students observe that movement of a solute in the solvent increases the rate of dissolution. They demonstrate that when the solute is broken into smaller pieces it dissolves faster.

In this solutions worksheet, students compare situations that increase or decrease the solubility of a solute. Students describe how surface area, stirring, and temperature can increase the rate of dissolving a solute. This worksheet has...

In this dilution worksheet, students determine the final concentrations of solutions after a specific amount of water has been added. This worksheet has 4 problems to solve.

In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...

In this solutions worksheet, students review types of solutions, concentration and saturation of solutions, and suspensions and colloids. This worksheet has 10 fill in the blank, 7 multiple choice, and 6 short answer questions.

Students elicit data on the water cycle, ocean topography, and island formation in this six lesson unit. The ocean floor and the properties of water are examined through a variety of discussions and hands-on experiments.

In this solutions worksheet, students brainstorm different types of solutions and an example of each type of solution. This worksheet is a graphic organizer.

In this mixtures worksheet, students access an activity on the web and record their answers from the web activity into a graphic organizer. Then students complete 2 short answer questions.

High schoolers model solutions with beakers of colored glass or plastic spheres. In this solutions lesson plan, students use beakers of colored spheres to represent pure substances. They mix the spheres to demosntrate solutions. They...

Why does some ink bleed through paper, and other ink doesn't? Practice some paper chromatography to separate the colors from a pen with an interactive experiment for middle and high schoolers. Learners use a variety of solutions to track...

There's no need to water down the resource. A tutorial takes learners through the process of creating dilutions for any solution. Specifically, it focuses on serial dilutions with successive factors of 10.

Encourage your classes to be laundry helpers! Learners explore the chemistry of stain removal with a lab investigation. By identifying the components of the stain, they identify the most effective solute for its removal.

Young scientists demonstrate their understanding of cell transport on this comprehensive worksheet. Focusing on cellular structure and the different processes that allow materials to move into, out of, and throughout animal...

When making sweet tea, why do people dissolve the sugar in hot tea instead of cold tea? The class discusses the previous lab and builds upon it. Working in groups, they design an experiment to determine how temperature affects the...

Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...

Examine the chemistry of the laundry room! A thorough video explains the polarity and non-polarity properties of soap. The tutorial continues to explain the advantage of these properties in stain removal by showing the...

Explore the importance of a concentration gradient in the rates of dissolution. Using the ocean ecosystem, learners study rates of dissolution around coral reefs. A hands-on experiment helps individuals discover the effects of changing a...

Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...

Students become acquainted with the principles of liquid chromatography and construct a liquid chromatography column. Students also investigate the effects of different solvents and solvent concentrations in the separation process.

In this solutions learning exercise, students answer 18 questions about solutions, saturation of solutions, solvents and solubility.
